Independent (UK)A lone gunman opened fire in a building at a small Seattle university, killing one person and injuring three others before being disarmed by a student, police have said.

The Seattle Police Department said Aaron Ybarra, 26, had been booked into King County Jail on Twitter following the shooting on Thursday.

Police said a student building monitor at Seattle Pacific University overpowered the gunman after he entered the foyer at Otto Miller Hall. When he began reloading his gun, the student subdued him with pepper spray, Capt. Chris Fowler of the Seattle Police Department said.

Several other students then jumped on top of the gunman and pinned him down until police officers arrived. Police said the monitor's actions and the actions of others prevented the tragedy from becoming even more serious.

AJCDennis Marx, 48, was part of an anti-government group that has been tied to violent attacks on law enforcement around the country, said Forsyth County Sheriff Duane Piper. Marx spelled out his problems with the agency in a lawsuit obtained by the Atlanta Journal-Constitution, and he was due in court Friday for a hearing on drug and weapons charges, official said.

Instead, they say Marx, armed with multiple explosives and lots of ammunition - and possibly wearing a bulletproof vest and gas mask - drove his SUV up to the courthouse. He threw out homemade smoke grenades, pepper spray grenades and spike sticks in an effort to keep law enforcement personnel from stopping his approach to the courthouse.

James Daniel Rush, a deputy working the doorway of the courthouse confronted Marx, who shot the officer in the leg through the windshield of his vehicle. Witnesses said Marx jumped from the SUV and started shooting his rife. Officers returned fire and Marx was dead.

So, guns can be "one" thing, especially by trained "good guys". But, as noted above, it's still not the "only" thing. And the folks up in Moncton, Canada know that's not the "guaranteed" thing to stop the "bad guy."
